Description

BACKGROUND OF THEINVENTION1. Field of the Invention

The present invention relates to a point-of-sale (POS) system and, more particularly, to a POS system with a display viewing angle adjustment device capable of adjusting a viewing angle of a display of the POS system with a more flexible range.

2. Description of the Related Art

To keep abreast with technological progress, cash registers back in early days with tiny display and primitive sale amount counting and receipt printing functions have been advanced to latest POS systems integrating touch screen, printer and a multitude of functions in handling transactions and inventory of merchandise as a whole, thereby boosting convenience of retail vendors or store clerks in keeping track of inventory and transactions of merchandise at all times.

With reference toFIG. 6, a conventional POS system includes abase90, asupport arm91 and atouch screen92 pivotally mounted on thesupport arm91. Because there is no enough space between thetouch screen92 and thebase90 for freely tilting thetouch screen92, the touch screen tends to hit thebase90, especially upon downward tilt of the touch screen, and is allowed for limited tilting angle adjustment. However, due to the differences in operator's height and/or operation environment, when a store clerk or a retail vendor is accessing customer pickup information or merchandise information and is also squatting to vendor to view the information on the display of the POS system while remaining in a squatting position because of the limited tilting range of thetouch screen92.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a point-of-sale (POS) system with a display viewing angle adjustment device allowing to conveniently adjust the display viewing angle of a display of the POS system.

To achieve the foregoing objective, the POS system with a display viewing angle adjustment device includes a screen, a fixing plate, a support plate and a base.

The screen has a rear cover.

The fixing plate is securely mounted on the rear cover of the screen and has two slide slots formed through the fixing plate.

The support plate is mounted between the rear cover of the screen and the fixing plate and has two side legs respectively formed on and protruding rearwards from a left edge and a right edge of the support plate and slidably mounted through the respective slide slots of the fixing plate to be movable within the respective slide slots in a downward or upward direction.

The base has a support arm pivotally connected with the side legs of the support plate.

According to the foregoing structure, when users intend to increase an adjustment range of display viewing angle of the screen, a measure using the support plate and the support arm to support the screen allows the screen to be further moved up through the slid slots. Such measure can increase movement space between the screen and the base and the adjustment range of display viewing angle as well. The combination of the fixing plate and the support plate increases the range of display viewing angle and therefore renders operational convenience to users in operation of the POS system.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

With reference toFIGS. 1 and 2, a point-of-sale (POS) system with a display viewing angle adjustment device in accordance with the present invention includes ascreen10, afixing plate20, asupport plate30 and abase40. Thefixing plate20 is securely mounted on arear cover11 of thescreen10. Thesupport plate30 is mounted between therear cover11 of thescreen10 and thefixing plate20. Thebase40 has asupport arm41 pivotally connected with the support plate30.Thescreen10 may be a touch screen.

With reference toFIGS. 2 and 3, thefixing plate20 has twoslide slots21, apivot seat22, arecess23,resilient element24, afirst positioning hole25, and anadjustment switch26. The twoslide slots21 are parallelly and vertically formed through thefixing plate20. Thepivot seat22 is mounted on a rear surface of thefixing plate20 and is located between the twoslide slots21. Therecess23 is formed in the rear surface of thefixing plate20 and is located above therecess23 and between the twoslide slots21. Theresilient element24 is inserted into therecess23. Thefirst positioning hole25 is formed through thefixing plate20 and is located below thepivot seat22 and between the twoslide slots21. Theadjustment switch26 is elongated in a vertical direction, is pivotally mounted on thepivot seat22, and has a pivotingportion261, apressing portion262 and apositioning protrusion263. Thepivoting portion261 is formed on a rear surface of theadjustment switch26 and is located between a top end and a bottom end of theadjustment switch26. Apin50 is mounted through thepivoting portion261 and thepivot seat22 of thefixing plate20 for theadjustment switch26 to be pivotable with respect to thepivot seat22. Thepressing portion262 is formed on the top end of theadjustment switch26, and corresponds to therecess23 of thefixing plate20. Thepositioning protrusion263 is formed on a front surface of theadjustment switch26, is located at the bottom end of theadjustment switch26, and corresponds to thefirst positioning hole25 of thefixing plate20. Before thepressing portion262 is pressed, thepositioning protrusion263 is kept in thefirst positioning hole25. When thepressing portion262 is pressed, thepressing portion262 is inserted into therecess23 and compresses theresilient element24 while thepositioning protrusion263 escapes from thefirst positioning hole25. After thepressing portion262 is released, the elastic restoring force of theresilient element24 ejects thepressing portion262 and thepositioning protrusion263 returns to thefirst positioning hole25. In the present embodiment, theresilient element24 is a spring.

Thefixing plate20 has four corners with one through hole formed through each corner. Therear cover11 of thescreen10 has four threaded holes formed in therear cover11 and corresponding to the four respective through holes of thefixing plate20. Four bolts are respectively mounted through thefixing plate20 and mounted in therear cover11 of thescreen10 to fasten thefixing plate20 on therear cover11 of thescreen10.

Thesupport plate30 has twoside legs31 and asecond positioning hole32. The twoside legs31 are respectively formed on and protrude rearwards from a left bottom edge and a right bottom edge of thesupport plate30, are respectively and slidably mounted through theslide slots21 of thefixing plate20 to be movable within therespective slide slots21 in a downward or upward direction, and are pivotally connected with two opposite portions of a top end of thesupport arm41 of thebase40, such that thescreen10 is supported by thesupport plate30 and thesupport arm41 and can be moved up and down along the twoslide slots21. Thesecond positioning hole32 is formed through thesupport plate30 and corresponds to thefirst positioning hole25 of thefixing plate20.

Thefixing plate20 further has multiple slotted holes vertically formed through thefixing plate20. Thesupport plate30 also has multiple threaded holes corresponding to the respective slotted holes of thefixing plate20, such that multiple bolts can be sequentially mounted through the respective slotted holes of thefixing plate20 and mounted in the respective threaded holes of thesupport plate30 for thesupport plate30 to be held between thescreen10 and thefixing plate20 and to be movable in downward and upward direction with respect to thefixing plate20.

With reference toFIG. 3, thesupport arm41 further has a pivotingmember42 mounted inside the top end of thesupport arm41. Thepivoting member42 is cylindrical and has twoleg rests421 respectively formed on and protruding outwards from a left end face and a right end face of the pivotingmember42. In the present embodiment, eachside leg31 has aguide slot33 formed in a free end of theside leg31, corresponding to one of theleg rests421, and pivotally connected to theleg rest421. The pivotingmember42 further has multiple threaded holes formed in the left end face and the right end face of the pivotingmember42. Eachside leg31 also has multiple threaded holes formed through theside leg31 and corresponding to the multiple threaded holes on one of the left end face and the right end face of thepivoting member42. Multiple bolts can be sequentially mounted through the respective threaded holes on theside legs31 of thesupport plate30 and the respective threaded holes on the left end face and the right end face of the pivotingmember42 to respectively fasten theside legs31 on the left end face and the right end face of the pivotingmember42, such that thescreen10 can be securely connected with thepivoting member42 upon being tilted.

With reference toFIGS. 4 and 5, operation of the POS system is described as follows. When thescreen10 is adjusted and lifted up to an upper limit point along a vertical direction, thepositioning protrusion263 of theadjustment switch26 engages thefirst positioning hole25 of thefixing plate20 and thesecond positioning hole32 of thesupport plate30. When thescreen10 is adjusted and lowered to a lower limit point along the vertical direction, thepositioning protrusion263 of theadjustment switch26 of theadjustment switch26 engages thefirst positioning hole25 of thefixing plate20 and abuts against a lower edge of thesupport plate30. Therefore, when moved up or down to the upper limit point or the lower limit point, thescreen10 can be fixed at the position.

When users intend to adjust viewing angle of thescreen10, supposing that thescreen10 is intended to tilt in a downward direction, thescreen10 needs to be lifted up in the vertical direction first. First of all, thepressing portion262 of theadjustment switch26 is pressed to compress theresilient element24. Thepositioning protrusion263 of theadjustment switch26 disengages from thefirst positioning hole25 of the fixingplate20 and the lower edge of thesupport plate30 and thescreen10 can be lifted up until thescreen10 reaches the upper limit point. Meanwhile, thesecond positioning hole32 of thesupport plate30 is aligned with thefirst positioning hole25 of the fixingplate20. After thepressing portion262 of theadjustment switch26 is released, the elastic restoring force of theresilient element24 brings thepositioning protrusion263 back to thefirst positioning hole25 of the fixingplate20 and thesecond positioning hole32 of thesupport plate30, thereby securing thescreen10 fixed at the adjusted viewing angle and ruling out the chance of sliding movement.

Because a movement space between thescreen10 and thebase40 is available after users lift up the screen vertically, the movement space allows thescreen10 to tilt down. Given the foregoing structure and operation, tilting angle of the screen becomes more flexible and the range of viewing angle of the screen can be further increased.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
